Slide 4: REVIEW Triangle : Triangle It is a three sided polygon. A B C AC AB BC Samples of Triangles that can be seen around us. : Samples of Triangles that can be seen around us. Slide 7: TYPES OF ANGLES Slide 8: Acute Angle -It is an angle whose measure is less than 900. 300 A B C <BAC which is an acute angle. Right Angle : Right Angle -It is an angle whose measure is equal to 900. 900 Obtuse Angle : Obtuse Angle - It is an angle whose measure is greater than 900 but less than 1800. 1500 How can we say that two segments are Congruent ? : How can we say that two segments are Congruent ? Slide 12: *Two segments are congruent if and only if they have equal length. C D 10 cm 10 cm measure of AB = measure of CD A B CLASSIFICATION OF TRIANGLES : CLASSIFICATION OF TRIANGLES According to angles According to sides Slide 14: TRIANGLES ACCORDING TO THERE ANGLES *ACUTE TRIANGLE : 600 48O *ACUTE TRIANGLE -All the angles of the triangle are acute. J L K 720 <J,<K,<L are all acute angles. RIGHT TRIANGLE : RIGHT TRIANGLE -An angle in a triangle is a right angle. 900 M O N <M is a right angle. leg leg The side opposite the right angle of a right triangle is called the hypotenuse. The other sides are called legs. HYPOTENUSE OBTUSE TRIANGLE : OBTUSE TRIANGLE - An angle in a triangle is an obtuse angle. P Q 1280 <P is an obtuse angle. R Slide 18: Triangles According to there sides SCALENE TRIANGLE : SCALENE TRIANGLE -No two sides are congruent. A B AB = BC = CA 4 cm 6 cm C 9 cm ~ ~ ISOSCELES TRIANGLE : D F ISOSCELES TRIANGLE -two sides of the are congruent. E DE = FE base leg leg The two equal sides of an isosceles triangle are called legs. The third side is called the base. ~ EQUILATERAL TRIANGLE : EQUILATERAL TRIANGLE -Three sides are congruent.
